Description

Technical Field

[0001] This utility model relates to the field of lignin processing technology, and in particular to a granule drying device for the production of lignin dispersants. Background Technology

[0002] Lignin is a complex organic polymer that forms an important structural material in the supporting tissues of vascular plants and some algae. Lignin is particularly important in cell wall formation, especially in wood and bark, as it imparts rigidity and resistance to decay. Chemically, lignin is a cross-linked phenolic polymer.

[0003] In the production and processing of lignin dispersants, in order to improve the quality of the finished product, it is also necessary to use a drying device to dry the granular raw materials required for production, so as to ensure the dryness and stability of the finished lignin dispersant. However, the granular raw materials commonly found on the market tend to accumulate in the device when the granular raw materials of lignin dispersants are poured into the device, resulting in uneven heating of the raw materials. After the outer layer of raw materials is dried, the inner raw materials are still damp. Moreover, the device has low processing efficiency and the raw materials are inconvenient to collect.

[0004] Therefore, it is necessary to develop a particle drying device for the production of lignin dispersants to address the aforementioned shortcomings. Utility Model Content

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0036] Please see Figure 1-3This utility model provides a technical solution: a granule drying device for producing lignin dispersant, comprising: a drying cylinder 1, the top of the drying cylinder 1 having a first opening 101 for pouring and discharging materials, and the bottom of the drying cylinder 1 having a second opening 102. Both the top and bottom of the drying cylinder 1 have a necked structure for material aggregation. A detachable auxiliary balancing structure is provided on the side of the drying cylinder 1 to prevent shaking during operation. When it is necessary to rotate the drying cylinder 1, the auxiliary balancing structure can be removed; further details are omitted here.

[0037] The heating tube 11 is connected to the inner wall of the drying cylinder 1. There are multiple heating tubes 11 arranged in an array around the rotating shaft 6 to quickly dry the material in the drying cylinder 1.

[0038] The first rotating component is externally driven to the drying cylinder 1 and is used to rotate the drying cylinder 1 so that the material inside the drying cylinder 1 can be dried evenly, or to make the first opening 101 face downwards so that the material can be discharged.

[0039] The second rotating component is rotatably disposed inside the drying cylinder 1 and is used for stirring and / or dispersing materials. The second rotating component is made of a heat-conducting metal material to facilitate the drying of the materials inside.

[0040] Compared with the prior art, this utility model, by setting a first rotating component, can rotate the drying cylinder 1 to facilitate the uniform drying of the material inside the drying cylinder 1, or to make the first opening 101 face downwards for easy material discharge; by setting a second rotating component, it can be used to stir and disperse the material, so that the material is dried evenly. This solves the problem in the prior art that when granular raw materials of lignin dispersant are poured into the device, the raw materials tend to accumulate in the device, resulting in uneven heating of the raw materials and the inner raw materials remaining damp after the outer layer of raw materials is dried.

[0041] In one embodiment of this utility model, the first rotating assembly includes: a first support column 2 and a second support column 9, which are spaced apart on both sides of the drying cylinder 1. A first connecting rod 8 and a second connecting rod 10 are symmetrically arranged on both sides of the drying cylinder 1; the first connecting rod 8 has a first opening 12, and the second connecting rod 10 has a second opening 13.

[0042] One end of the first connecting rod 8 is connected to the outer wall of the drying cylinder 1, and the other end of the first connecting rod 8 is rotatably connected to the first opening 12 through a bearing; the first support column 2 is connected to the side away from the drying cylinder 1 by the first drive motor 3, which is located close to the first opening 12, and the drive end of the first drive motor 3 is rotatably connected to the first connecting rod 8; one end of the second connecting rod 10 is connected to the outer wall of the drying cylinder 1, and the other end of the second connecting rod 10 is rotatably connected to the second opening 13 through a bearing.

[0043] Compared with the prior art, the present invention drives the first connecting rod 8 to rotate through the first drive motor 3, thereby causing the drying cylinder 1 to rotate around the first connecting rod 8. On the one hand, the material in the drying cylinder 1 can be shaken evenly, and on the other hand, by flipping the drying cylinder 1, the first opening 101 faces downward, which facilitates the discharge of material.

[0044] In one embodiment of this utility model, the second rotating assembly includes: a second drive motor 5 connected to the outer side of the bottom of the drying cylinder 1; a rotating shaft 6 vertically disposed inside the drying cylinder 1, the bottom end of the rotating shaft 6 being rotatably connected to the second opening 102 via a bearing; and the top of the rotating shaft 6 being spaced a predetermined distance from the first opening 101.

[0045] A spiral blade 4 is wound around a rotating shaft 6; a feeding cylinder 7 is fitted over the outer gap of the spiral blade 4, with the top of the feeding cylinder 7 spaced a predetermined distance from the first opening 101 and connected to the top of the drying cylinder 1 via a fixing rod 14; a discharge port 701 is provided on the side of the feeding cylinder 7 near the top, and a feed port 702 is provided at the bottom of the feeding cylinder 7. Multiple discharge ports 701 are arranged in an array around the rotating shaft 6. The spiral blade 4 wound around the rotating shaft 6 at least 6 turns, maximizing the uniform dispersion of the material.

[0046] This invention uses a second drive motor 5 to drive the rotating shaft 6 to rotate, which in turn drives the spiral blades 4 to rotate. This allows the material at the bottom of the drying cylinder 1 to enter the conveying cylinder 7 from the feed inlet 702 and be conveyed upwards by the spiral blades 4. After the material is discharged from the discharge outlet 701, it falls back to the bottom of the drying cylinder 1 and is conveyed upwards again by the spiral blades 4. This process is repeated to circulate and disperse the material accumulated at the bottom of the drying cylinder 1, thereby improving the drying effect.

[0047] This embodiment provides a method for using a granule drying device for lignin dispersant production, as detailed below:

[0048] Turn on the heating element 11, pour the material into the drying cylinder 1 through the first opening 101, then close the first opening 101. Start the second drive motor 5, which drives the rotating shaft 6 to rotate, causing the spiral blades 4 to rotate. This allows the material at the bottom of the drying cylinder 1 to enter the conveying cylinder 7 through the feed inlet 702, be conveyed upwards by the spiral blades 4, and then discharged from the discharge outlet 701 back to the bottom of the drying cylinder 1. The material is then conveyed upwards again by the spiral blades 4. This process is repeated to circulate and disperse the material accumulated at the bottom of the drying cylinder 1, improving the drying effect. After drying, start the first drive motor 3, which drives the first connecting rod 8 to rotate, causing the drying cylinder 1 to rotate around the first connecting rod 8. By flipping the drying cylinder 1, the first opening 101 faces downwards, facilitating the discharge of material.
